You could extend your attitude to any sort of disability couldn't you. Why hire someone in a wheelchair, when there is someone who could walk up the stairs in half the time?

Can the person in the wheelchair code fizzbuzz in an interview?

"Can they code it on the job" is the relevant question.

You can take the guy who starts frothing at the mouth when you ask him to code fizzbuzz, I’ll take the wheelchair guy who can code fizzbuzz during the interview. Deal?

When did anyone start frothing at the mouth?

Does it bother you that you don't know the answer?

Communicating in the office is quite different than communicating in an interview setting.

In your head and the head of those with extreme anxiety it is quite different. You're meet people who might be nice or not and chat a bit, you answer some questions, maybe there's a free lunch involved, you either get a job offer or you don't and you continue your search, and your life continues on without the sky collapsing

You could say that for almost any job, but somehow you don't see the same hyperbolic whinging in all of those fields, do you? And your claim isn't even true. It's very similar to the kind of code discussion you might have on the job. "How would you solve this?" "What if I try X, Y, and Z?"

This whole thing reminds me of a shitty superhero spoof movie from the 90’s - Mystery Men - one of the characters’ superpower is that he can turn invisible when nobody else is looking and he is naked
